l dont know where else to ask this as /a/ will for sure tell me to fuck off or ban me

In the anime Mononoke the medicine seller guy wears a different style of clothing than everyone else, and resources online say it's anachronistic, from a much older period, in the style of animist shamans (also suggested by the facial marks) -- l suppose before or around the arrival of Buddhism to Japan. which points towards the Kofun or Asuka period probably?
